Chapter II startup and shutdown class failure

An example of a definition

Failures related to startup and shutdown procedures. Startup is the problem that occurs from the completion of the self-test to the application interface of the operating system; shutting down the system is the process of switching from a click to a power disconnect.

Second, possible phenomenon of failure

1, start the process of panic, error, black screen, repeated restart, etc.

2, the start-up process reported a file error;

3, in the start-up process, always perform some inappropriate operations (such as always disk scan, start an abnormal application, etc.);

4, only in Safe Mode or command line mode to start;

5, login failure, error or panic;

6, shut down the operating system when the panic or error.

Iii. parts that may be involved

BIOS settings, startup files, device drivers, operating system/application configuration files, power supplies, disk and disk drives, motherboards, signal cables, CPUs, memory, and other possible board cards.

Iv. Points of judgement/order

1, before the maintenance of the preparation

1) disk data cable;

2) Multimeter;

3) virus-checking software.

2. Environmental inspection

1 machine peripheral and appearance inspection:

A. Whether the mains connection is sad, should not be too loose or not inserted in place phenomenon;

B. The host hard drive indicator is correct and shiny, should not be not bright or often bright phenomenon;

C. Observe whether the system has peculiar smell, the component temperature is high;

D. Observe the speed of the CPU fan is not enough, or whether it is too slow or unstable;

E. Listen for noise when working on the drive.
